ACTUAL SELECTED OEI STOP refers to the power limit up to which the idled engine can provide power.

• A. ACTUAL SELECTED OEI STOP
• B. The power limit of the good engine
• C. The minimum idle value
• D. The maximum continuous torque

Answer: (A)

In OEI (one engine inoperative) operations, the aircraft imposes a specific ceiling on how much power the remaining engine is allowed to deliver to keep rotor speed and controllability within safe margins. The Actual Selected OEI Stop is exactly that ceiling—the power limit up to which the idled/failed engine’s contribution is considered or allowed in the OEI configuration. This value is determined from performance data and the current flight setup, and it sets the limit you must stay under when one engine is not producing full power.

This is distinct from the good engine’s maximum capability (which is the overall power the functioning engine could provide under full power conditions), from any minimum idle setting (which isn’t the OEI protection limit), or from the general maximum continuous torque (a broad rating not specific to OEI operation). The Actual Selected OEI Stop specifically defines the OEI power cap for safe flight with one engine out.
